Research on Fuel Cycle of Thorium Advanced CANDU Reactor

The fuel cycle model is one of the most important problem in the concept design of Thorium Advanced CANDU Reactor(TACR).(Th-U)O2 CANFLEX fuel bundle,with ThO2 elements in the inner two rings and slightly enriched uranium(SEU)elements in the outer two rings,was used in the design of TACR.According to the research on the lattice physics of this fuel bundle,a feasible direct self-recycle method was researched for this Th-U fuel bundle.
